If you locate the topic among the
downloads on the Hullabaloo and post a link to the exact topic that has the one you're thinking of, it's lot easier than guess which one we're looking for; and of course much easier for me to find.
A dorm, eh? Let's see... That might be
Harrington Hall or
Parkview Dormitory or
Raleigh Residence Hall.
I remember building that tiny dorm that had nothing but rooms to sleep in but if it's in the Downloads area, I must be overlooking it. I think I called it "Microdorm." But I'm not sure that I ever packaged it up as a download.
